"Cynical is lying in the ruck and just staying down and trying not to roll away, taking the ball out of a ruck which you're not allowed to do," he said.
To make matters worse for the Blues, who have not won an away game since June 2014, skipper Jerome Kaino will be ruled out for up to four weeks with a sprained AC shoulder joint.
The Blues have a bye next weekend, but he won't be available for the match against the Jaguares at North Harbour Stadium the week after.
Umaga defended his decision to go for the draw via Ihaia West's penalty after the final hooter, rather than go for touch and a possible try to win it, and he was backed up by assistant coach Glenn Moore today.
"That was a decision we made in the box," Moore said. "It was right on full-time and we didn't want to take the risk of throwing the ball not straight or whatever at the lineout and coming away losing the game.
"We drew the match but it feels like a loss at the moment. We created some very good opportunities, some clear-cut ones, in the first half but unfortunately we didn't convert those into points. It is frustrating.
"It was there for the taking. We had a plan and we created opportunities and on a few occasions we didn't execute those. But there were also a number of positives there. We were down 25-15 with not long to go and we had young boys out there but we really dug deep and clawed our way back into it so there pleasing aspects there as well."
The draw snapped a two-match losing streak for the Blues, who began brightly, with West scoring an early converted try, but despite the confusion around Lees' rulings they were again the architects of their own demise. Errors combined with poor decision-making meant they couldn't maintain their early momentum and the players and supporters might wonder when their first win away from home will come.
Their next away match is against the Chiefs in Hamilton on April 8, a tougher assignment than the Reds who have yet to win this season.
